Forge
The agent layer that builds the supply at machine pace.
Forge is the agentic build environment for constructing apps on Frame. It is the operational form of the shift behind the whole suite: humans build the agents, and the agents build the apps.
Agents work in two modes. In Compose, they select and parameterise existing Frame components to assemble an app against a spec. In Extend, they propose new components when the library does not yet cover a need. Human supervision happens at the boundaries (at scope changes and component admission), not on every line.
Forge is separable: a customer can run Frame with human developers and no Forge at all. A Datastake-style deployment uses both, which is how the ecosystem can add apps in hard sectors faster than headcount ever allowed.
Where it sits. Depends on Frame as the surface it builds against. Independent of Spine and Scribe; a Frame deployment does not require it.
